<p></p>
  The ILayoutManagerClient interface defines the interface 
  that a component must implement to participate in the 
  LayoutManager's commit/measurement/layout sequence.  
   <p>Objects that implement this interface can be passed to the
  LayoutManager's <code>invalidateProperties()</code> method.
  When the LayoutManager reaches the commit properties phase,
  the LayoutManager invokes this object's <code>validateProperties()</code>
  method.</p>
   <p>Similarly, if an object is passed to the LayoutManager's
  <code>invalidateSize()</code> method, then the LayoutManager
  calls that object's <code>validateSize()</code> method
  during its measurement phase, and if an object is passed
  to LayoutManager's <code>invalidateDisplayList()</code> method,
  then the LayoutManager  calls its <code>validateDisplayList()</code> method 
  during the layout phase.</p>
   <p>The ILayoutManagerClient interface is implemented by the UIComponent 
  and ProgrammaticSkin classes.</p>

   The top-level SystemManager has a nestLevel of 1.
   Its immediate children (the top-level Application and any pop-up
   windows) have a <code>nestLevel</code> of 2.
   Their children have a <code>nestLevel</code> of 3, and so on.  
     The <code>nestLevel</code> is used to sort ILayoutManagerClients
   during the measurement and layout phases.
   During the commit phase, the LayoutManager commits properties on clients
   in order of decreasing <code>nestLevel</code>, so that an object's
   children have already had their properties committed before Flex 
   commits properties on the object itself.
   During the measurement phase, the LayoutManager measures clients
   in order of decreasing <code>nestLevel</code>, so that an object's
   children have already been measured before Flex measures
   the object itself.
   During the layout phase, the LayoutManager lays out clients
   in order of increasing <code>nestLevel</code>, so that an object
   has a chance to set the sizes of its children before the child
   objects are asked to position and size their children.
